Mid-term outcomes of minimally invasive surgery for partial atrioventricular septal defect in children

Objective: This study aims to describe the mid-term outcomes of minimally invasive surgery for partial atrioventricular septal defect in children. Summary: Partial atrioventricular septal defect is one of the three types of atrioventricular septal defect, accounting for about 3.5% of congenital heart disease. Traditionally, complete repair has been performed via sternotomy. However, with the advancement of minimally invasive surgical techniques in treating congenital heart conditions, we conducted this study to assess the feasibility and mid-term outcomes of this approach. Subjects and methods: This descriptive study spanned from January 2018 to December 2023, involving 30 patients diagnosed with partial atrioventricular septal defect who underwent minimally invasive complete repair. The cohort comprised 12 males and 18 females, with an average age of 18 months and average weight of 10.3 kg. The mean diameter of the primary atrial septal defect was 15 mm. Eight patients (26.7%) exhibited moderate to severe mitral regurgitation, and the average pulmonary artery pressure was 37 mmHg. Results: The average durations of cardiopulmonary bypass and aortic cross-clamp were 82 minutes and 58 minutes, respectively. None of the patients required sternotomy. The average time of artificial ventilator post-surgery was 6.9 hours, with a mean hospital stay of 7.6 days. Postoperative echocardiography showed promising results: complete closure of atrial septal defect, with 90% of patients having absent or mild mitral valve regurgitation, only 10% experienced moderate mitral valve regurgitation. The average follow-up period was 38 months, during which there were no postoperative fatalities. One patient required reoperation due to severe mitral regurgitation from an anterior cleft. Conclusion: Minimally invasive surgery for partial atrioventricular septal defect in children can be safely performed, yielding favorable mid-term outcomes during follow-up.

Correlation between types of ventricular septal defect and chromosomal abnormalities in low-risk non-invasive prenatal testing.

The aim of this study was to examine whether there is a correlation between different types of ventricular septal defects (VSD) and chromosomal abnormalities in the low-risk setting of non-invasive prenatal testing (NIPT) and to evaluate the prognosis of fetuses with varying types of VSD. Cases of pregnant women who underwent amniocentesis due to fetal VSD were collected by Tianjin Central Hospital of Obstetrics and Gynecology from May 2017 to May 2022. Exclusions were made for those without NIPT, with high-risk NIPT results, genetic disorders, and those lost to follow-up. Data collected included ultrasound classification of VSD, prenatal NIPT results, copy-number variations (CNVs) results, and neonatal outcomes. The prevalence of pathogenic CNVs was investigated in 74 cases of VSDs. Of these cases, 45 were isolated VSDs (9 muscular and 36 non-muscular) and 29 were non-isolated VSDs (10 with intracardiac and 19 with extra-cardiac structural anomalies). The results revealed that the incidence of pathogenic CNVs was lower in isolated VSDs compared to non-isolated VSDs in a low-risk NIPT condition (χ2 = 9.344, P = 0.002). There was no significant difference in the prevalence of pathogenic CNVs between VSDs with intracardiac and extra-cardiac structural anomalies (P = 0.541). Moreover, VSDs associated with intracardiac structural anomalies had the highest rate of surgical intervention. When NIPT is low-risk and VSD is isolated, the likelihood of fetal chromosomal defects is not increased. However, if there are intra- or extra-cardiac structural abnormalities present alongside VSD, the possibility of pathogenic CNV is considerably greater, necessitating invasive prenatal diagnosis. Isolated muscular VSDs usually do not require surgery, which can be used as a basis for prenatal counseling regarding fetal VSD.

Pulmonary Hypertension in Pregnancy: A Cardiological Approach to Maternal Outcomes as well as Neonatal and Therapeutic Management

Highlights: 1. Pulmonary hypertension is threatening to both the mother and the infant in the womb. 2. This report discusses the complexity of physiological changes in pregnant women with pulmonary hypertension. - Abstract Background: Maternal morbidity and mortality with pulmonary hypertension in pregnancy usually occur during labor until early postpartum. Historical reports have shown mortality rates as high as 30–56%. We report a 32-year-old female patient pregnant with her second child, with complaints of bleeding from the birth canal since 1 hour before admission to the hospital and a history of atrial septal defect type secundum. Case presentation: The patient was diagnosed with G2P1A0, 16–17 weeks pregnant, with death conception, thrombocytopenia, and ASD secundum with pulmonary hypertension. The patient was planned for dilation and curettage by the obstetrics and gynecology departments. As a result of consultation with the cardiology department, medication management was given, and the decision to tolerate CRI IV very high-risk surgery was given. Conclusion: Despite progress, pregnancy remains poorly tolerated in cases of pulmonary hypertension. Management should remain focused on contraceptive counseling and offering early termination when pregnancy does occur

Ventricular Septal Defects: Molecular Pathways and Animal Models.

Ventricular septation is a complex process which involves the major genes of cardiac development, acting on myocardial cells from first and second heart fields, and on mesenchymal cells from endocardial cushions. These genes, coding for transcription factors, interact with each other, and their differential expression conditions the severity of the phenotype. In this chapter, we will describe the formation of the ventricular septum in the normal heart, as well as the molecular mechanisms leading to the four main anatomic types of ventricular septal defects: outlet, inlet, muscular, and central perimembranous, resulting from failure of development of the different parts of the ventricular septum. Experiments on animal models, particularly transgenic mouse lines, have helped us to decipher the molecular determinants of ventricular septation. However, a precise description of the anatomic phenotypes found in these models is mandatory to achieve a better comprehension of the complex mechanisms responsible for the various types of VSDs.

Adults knowledge and perception of their congenital heart disease: a single center cross-sectional study

Abstract Background A great proportion of patients with congenital heart disease (CHD) reach adulthood and face daily challenges living with a chronic illness. Healthcare management of these patients is complex requiring a multidisciplinary approach. To date, few studies have focused on adult patients’ understanding of their CHD. Aim To assess adults’ knowledge of their CHD on 4 domains: (1) disease and treatment, (2) preventive measures, (3) physical activity, (4) reproductive issues. Methods One single center cross-sectional study. Patients were opportunistically recruited to participate in the study at their CHD medical visit, between October 2022 and December 2022. The authors translated Leuven Knowledge Questionnaire for CHD to Portuguese language. Patients that were willing to participate filled the survey before entering the physician’s room. Demographic and clinical variable were gathered during patients’ interview and from clinical records. After run-in period, data were analyzed in SPSS ® for the descriptive analysis. Categorical values were reported as counts and percentages. Results From a total of 344 patients observed during recruitment period, 97 accepted to participate in the study. Demographic and clinical characteristics of the study population are described in Table 1 and 2. Mean age was 41 years, 60% were female, 34% have an education level above 12th grade and 74% are employed. The 3 most prevalent CHD were Tetralogy of Fallot (16%) and atrial septal defect type secundum (13%) and ventricular septal defect (10%). Approximately half of the patients knew the name of their CHD and 41% could describe or locate the lesion on the pictured diagram. 38% could identify at least two symptoms of clinical deterioration. Three-fourths of patients did not know what endocarditis is and only 14% could tell fever was the main symptom of the disease. The majority of patients did not know the risk factors for endocarditis. 73% of patients are aware that they should choose an occupation adequate to their physical status and 75% knew that they are allowed to engage in sexual intercourse if capable of doing so. Only 20% had adequate knowledge about the hereditary nature of their condition. 43% of women knew the risk of clinical deterioration during pregnancy. Conclusion This study showed our patients have high levels of education and employment. Still, large proportions of adults have lack of knowledge about important issues in vary domains. These findings reinforce the need to improve patients’ education about their disease. In addition, it highlights the importance of guideline recommendations on multidisciplinary teams to achieve high quality of care in adults with CHD.

Echocardiographic Study of Ventricular Septal Defect in 1- to 12-Year-Old Children Visiting a Tertiary Care Center in Patna, India.

Background Symptoms of serious heart problems present at birthoften appear during the first few days, weeks, or months of a child's life. Shunt formation between the left and right ventricle is a crucial component of the pathophysiology of ventral septal defects. Objectives We aim to determine the most frequent types of ventricular septal defect (VSD) by echocardiography and whether there is any gender variation in the type of ventricular septal defect. Material and methods A total of 100 children who were clinically suspected of or diagnosed with VSD at the age of 1-12 years were enrolled in this study. The septum of the atrioventricular (AV) canal, the muscular septum, and the parietal band of the distal conal septum were evaluated by color Doppler. Ventricular septal defect (VSD) size and kind are similarly impacted by the 2D echo mode. The size and site of the VSD, associated congenital anomaly, and significant morphological changes in ventricular cavities, gender discrimination, and relation-specific types of ventricular septal defect were observed. Results A total of 100 VSD children presentedwith clinical symptoms of fast breathing, retraction of the chest, cough, cyanosis, fever, difficulty during feeding, cyanotic spell, chest pain, and edema at 65%, 62%, 54%, 52%, 54%, 29%, 9%, 11%, and 4%, respectively. Conclusion Early diagnosis is essential for effective medical care of diseases such as infective endocarditis (IE), which is present in some cases of VSD, and the avoidance of persistent pulmonary veno-occlusive disease (PVOD).

Ventricular septal defect in octogenarian: a case report

It is not a common case that we see in our day-to-day clinical practice, a patient presenting with congenital VSD at the age of eighty. Ventricular septal defect (VSD) is a developmental defect of the interventricular septum resulting from a deficiency of growth or a failure of alignment or fusion of component parts of ventricular septum.1Ventricular septal defects are the most common form of congenital heart disease and among the most frequently seen congenital abnormalities.2Perimembranous defects are the most common types of ventricular septal defects and account for 80% of such defects.3It is estimated that 25–40% of VSDs will close by the age of 2 years, and they are unlikely to persist after the age of 10 years; thus adults with congenital heart disease, VSDs represent only about 10% of the cases.4

P269 AORTA–RIGHT ATRIAL TUNNEL POST TRICUSPID ANNULOPLASTY

Abstract Background Aorta–right atrial tunnel is a rare entity characterized by a iatrogenic vascular fistula, which connects aortic root and right atrium. It is frequently associated with congestive heart failure (HF). Case A 54 y female with an history of atrial septal defect (ASD) type ostium secundum closure and a recent mitral and tricuspid annuloplasty surgery, presents to the hospital with significant decrease in exercise tolerance and progressive shortness of breath. At the presentation, physical examination was significant for tachycardia, continuous murmur over precordium and lower extremity edema. ECG showed right ventricular pressure overload with repolarization abnormality. TTE showed moderate systolic flattening of the septum and dilated right sections. Non coronary cusp of aortic valve demonstrated a perforation extending to the right atrium (RA). ETE confirmed the connection between non–coronary aortic cusp and RA, furthermore revealed unkown sinus venosus type ASD. TC angiography showed a marked dilation of the pulmonary artery trunk (egg and banana sign) and a connection between aorta and RA. She was treated with surgical closure of aorta– right atrial tunnel and ASD through detached and pledget stitch closure. Follow–up reveals significant functional recovery of shortness of breath and exercise tolerance. Discussion Aorta– right atrial tunnel is a rare entity characterized by a vascular fistula, which connects one of the sinuses of Valsalva and the RA. It is a rare complication of tricuspid plastic surgery. It is classified according to its relation to the aorta to anterior or posterior. The clinical presentation ranges from asymptomatic continuous murmur to the symptoms of right sided HF. In our case, the presence of ASD accelereted and worsened the manifestations of right HF. It is usually diagnosed by TTE or ETE, TC angiography and aortography. The treatment of this condition is important even in asymptomatic cases due to the risk of aortic valve dysfunction, likely regurgitation, congestive right sided HF followed by left sided HF, calcification, infective endocarditis, aneurysmal dilatation and pulmonary hypertension. Conclusion The possibility of complications of aorta–right atrium fistula necessitates early therapy, even in asymptomatic patients or those with a hemodynamically insignificant shunt. Available treatment is surgical closure. It has a high mortality rate if it is not diagnosed adequately and surgically treated without delay.

Rzadki przypadek podwójnej przegrody międzyprzedsionkowej u 4-letniego chłopca z dużym ubytkiem przegrody międzyprzedsionkowej typu ostium secundum

The work presents a case of a 4-year-old boy diagnosed with a large atrial septal defect type ostium secundum (ASD2) and additional abnormal structures in the direction of the left atrium in the echocardiogram. The patient was qualified for interventional defect closure, however, in the transoesophageal echocardiography, in addition to a very large ASD2 (approx. 2 cm), a double interatrial septum was diagnosed. The extra wall layer was parallel to the atrial septum and did not obstruct blood flow from the pulmonary veins or through the mitral valve. No signs of clotting material were observed in the space between the two layers. The closure was withdrawn during cardiac catheterization and the boy was qualified for scheduled surgery. Currently, the boy is asymptomatic and leads a normal lifestyle.

Comparative study, using transthoracic echocardiography versus left ventriculography to assesses ventricular septal defect eligibility for device closur

Accurate evaluation of ventricular septal defects types (locations) and measurement of the size of ventricular septal defects and distance from ventricular septal defects to aortic valve are essential for successful trans catheter device closure. The aim of study to assess in patient with ventricular septal defects the accuracy of transthoracic echocardiography in determining the size, position (type), and the distance from ventricular septal defects to the aortic valve as compared to trans- catheter approaches. Cross sectional study included patients with a diagnosis of ventricular septal defects with specific criteria suitable for treatment with transcatheter device closure. Eligibility was confirmed during this study and subject demographic (age, sex), growth parameters (height, weight, body surface, and body mass index) were extracted. During study period, patients underwent catheterization for device closure. Prior to catheterization two- dimensional echocardiography evaluation of VSD was done then left ventriculography was performed by interventional pediatric cardiologist to accurately determine the ventricular septal defects location (type), size and the distance from ventricular septal defects to the aortic valve. Sixty-three patients with in ventricular septal defects. The sensitivity of transthoracic echocardiography in detection the types ventricular septal defects of compared to catheter- based assessment (left ventriculography) was (100%) for all types of ventricular septal defects. The correlation coefficient sensitivity of assessment of ventricular septal defects size by transthoracic echocardiography compared to catheter-based assessment was (97%) p-value (0.001*). The correlation coefficient sensitivity of distance of ventricular septal defects to the aortic valve measured by transthoracic echocardiography compared to catheter based measurement was (91 %) p-value (0.001*). Conclusion: Transthoracic echocardiography is useful to evaluate VSDs location and useful to assess measurements of ventricular septal defects prior to transcathetered occlusion. Irregularity of ventricular septal defects shape and its changes during cardiac cycles are sub-optimally estimated by trasthoracic echocardiography.

Is It The Blame of The Occluder? Two Cases of Massive Thrombosis in the Left Atrium in Patients with Bioprosthetic Mitral Valve and the Presence of the Occluder Implanted Percutaneously

In the following case report, we present two clinical cases of patients after valvular intervention and percutaneous occluder implantation into the left atrium. The first patient is a 68-year-old male admitted to the Department of Cardiology because of Non-ST-Elevation Myocardial Infarction (NSTEMI). He had a medical history of paroxysmal atrial fibrillation and implantation of a biological mitral prosthesis due to severe secondary mitral regurgitation. Due to contraindications to the chronic use of anticoagulants, the patient underwent percutaneous closure of the left atrium appendage. The second patient is an 80-year-old man with a history of permanent atrial fibrillation. 8 years ago, the patient underwent percutaneous atrial septal defect type II (ASD II) closure with and the Amplatz occluder. A year later, the patient underwent Coronary Artery Bypass Graft (CABG) and biological mitral valve implantation due to multivessel coronary disease accompanied by severe mitral regurgitation. In both patients, Transthoracic Echocardiogram (TTE) showed massive thrombosis in the left atrium.

P314 WHEN TAKO–TSUBO TRAPS… NOT ONLY OCTOPUSES

Abstract The case we present involves a 75 years–old woman with no cardiological past medical history, who presented to our attention complaining of sudden onset thoracic pain associated with dyspnea, dry cough, nausea and an episode of vomit. She called 911 rapidly coming to our Hospital. In the Emergency room an EKG showed ST segment depression in the inferior leads and in the blood test a remarkable increase in HS–Troponin level was evident. An echocardiogram showed mid and apical left ventricle segments hypokinesia with moderately reduced Ejection Fraction (45%); notably, right ventricle was increased in dimension with moderate tricuspid regurgitation and mild pulmonary hypertension. Because of this last find, D–dimer was checked and a pulmonary angio– CT was performed which excluded active pulmonary embolism. Next day she underwent coronary angiography which showed no coronary lesion able to explain the clinical and echocardiographic presentation; left ventriculography was also performed showing an increase in end–systolic volume with hypokinesia of the anterolateral, apical and diaphragmatic walls and an Ejection Fraction (EF) of 30%. These findings allowed us to make the diagnosis of Tako–Tsubo syndrome, also known as stress–induced cardiomyopathy. Few days later, a cardiac magnetic resonance (CMR) was performed showing whole apical and antero–lateral mid ventricular hypokinesia with compensatory hyperkinesia of basal segments; T2–weighted sequences were positive at the hypokinetic segments with no specific Late Gadolinium Enhanced (LGE) images. What’s more, an atrial septal defect type “ostium secundum” was clearly evident, causing a left–to–right shunt hemodynamically significant (Qp/Qs of about 2,8) with right atrial and right ventricle dilatation. Pulmonary artery and its main branches were dilated too. After these findings, lady underwent right heart cardiac catheterization that reported a Qp/Qs of 3,24 and a shunt flow of 8,78 L/min, with a cardiac index of 2,5 L/min/m2 and normal pulmonary vascular resistance (0,7 Wood Units). Because of these measures the patient was discharged from our Cardiology Unit and referred to the Interventional Cardiology centre of our city for the percutaneous closure of the hemodynamically significant atrial septal defect. This case is curious because it shows how things in Cardiology can be deeply and unpredictably connected.

Results of percutaneous closure with device in congenital heart disease of the atrial septal defect type

Congenital Interatrial Septal Defects (TEA) are among the most common Congenital Heart Diseases in the population, where Atrial Septal Defect stands out, which is produced by a left-right short circuit that provides greater survival and less morbidity and mortality. The objective was to determine the results of Percutaneous Closure with a Device in Congenital Heart Disease of the Atrial Communication type at the Carlos Andrade Marín Specialty Hospital (Quito) in the Hemodynamics service from January 2009 to July 2019. It is a retrospective descriptive cross-sectional study . With a population of 122 cases from the AS400 registry. Thus, it was determined: there is a female predominance in a ratio of 2:1, the ranges for defect intervention were 5.5 mm to 35 mm, post-procedure pulmonary artery pressures (systolic 18-25 mmHg and diastolic 6-10 mmHg) in 95% of patients, ventricular overload in 76% in pre-procedure patients. Concluding that 96% of our population has a significant post-procedure improvement.

Low serum 25-hydroxyvitamin D (vitamin D) level among children with ventricular septal defect: how big is the risk for pulmonary hypertension?

Ventricular septal defect is the most common CHD, leading to pulmonary hypertension. Significantly lower 25-hydroxyvitamin D level was reported in children with CHD compared with healthy controls. The current study aimed to investigate the correlation between 25-hydroxyvitamin D level and pulmonary hypertension in children with ventricular septal defect. A cross-sectional study was conducted on ventricular septal defect paediatric patients from January to June, 2019. Serum 25-hydroxyvitamin D was measured using electrochemiluminescence. Pulmonary hypertension was defined as mean pulmonary artery systolic pressure > 20 mmHg for children >3 months of age at sea level, measured by Doppler echocardiography. From forty-four subjects, the majority of the subjects were female (56.8%) with normal nutritional status and perimembranous ventricular septal defect. Bivariate analysis showed that 25-hydroxyvitamin D level was associated with pulmonary hypertension (p < 0.01), type and size of ventricular septal defect (p = 0.02), and heart failure (p < 0.01). Higher 25-hydroxyvitamin D level was correlated with better nutritional status (p = 0.04, r = 0.26), and lower 25-hydroxyvitamin D level was correlated with the occurence of perimembranous ventricular septal defect (p = 0.01, r = -0.39), larger defect size (p < 0.01, r = -0.70), history of pneumonia (p = 0.02, r = -0.31), and heart failure (p < 0.01, r = -0.64). Subjects with 25-hydroxyvitamin D deficiency had prevalence ratio of 24.0 times for pulmonary hypertension. Higher pulmonary artery pressure was correlated to the occurence perimembranous ventricular septal defect (p = 0.01, r = 0.47), larger defect size (p < 0.01, r = 0.78), history of pneumonia (p = 0.01, r = 0.38), and heart failure (p < 0.01, r = 0.75). Children with ventricular septal defect who had low 25-hydroxyvitamin D level posed a higher risk of having pulmonary hypertension.

Diagnostic challenges in Goldenhar syndrome – a case report

Goldenhar syndrome, also known as oculo-auriculo-vertebral syndrome, represents a rare congenital complex of anomalies, involving the development of the first and second brachial arches during the first embryonary stage. In addition to the craniofacial disorders, Goldenhar syndrome can include central nervous system, heart, skeleton or kidneys pathologies as well as vertebral defects. We present the case of a Goldenhar syndrome whose first pathologic sign was tetralogy of Fallot, with associated cardiovascular disorders (atrial septal defect type ostium secundum, and single umbilical artery) and bilateral microtia, with malformation of auditory canal, mandibular hypoplasia and a single epibulbar dermoid. The Goldenhar syndrome was diagnosed after birth, the article emphasizing the difficulties of prenatal diagnosis.

Key Regulatory Differentially Expressed Genes in the Blood of Atrial Septal Defect Children Treated With Occlusion Devices.

Atrial septal defects (ASDs) are the most common types of cardiac septal defects in congenital heart defects. In addition to traditional therapy, interventional closure has become the main treatment method. However, the molecular events and mechanisms underlying the repair progress by occlusion device remain unknown. In this study, we aimed to characterize differentially expressed genes (DEGs) in the blood of patients treated with occlusion devices (metal or poly-L-lactic acid devices) using RNA-sequencing, and further validated them by qRT-PCR analysis to finally determine the expression of key mediating genes after closure of ASD treatment. The result showed that total 1,045 genes and 1,523 genes were expressed differently with significance in metal and poly-L-lactic acid devices treatment, respectively. The 115 overlap genes from the different sub-analyses are illustrated. The similarities and differences in gene expression reflect that the body response process involved after interventional therapy for ASDs has both different parts that do not overlap and the same part that crosses. The same portion of body response regulatory genes are key regulatory genes expressed in the blood of patients with ASDs treated with closure devices. The gene ontology enrichment analysis showed that biological processes affected in metal device therapy are immune response with CXCR4 genes and poly-L-lactic acid device treatment, and the key pathways are nuclear-transcribed mRNA catabolic process and proteins targeting endoplasmic reticulum process with ribosomal proteins (such as RPS26). We confirmed that CXCR4, TOB1, and DDIT4 gene expression are significantly downregulated toward the pre-therapy level after the post-treatment in both therapy groups by qRT-PCR. Our study suggests that the potential role of CXCR4, DDIT4, and TOB1 may be key regulatory genes in the process of endothelialization in the repair progress of ASDs, providing molecular insights into this progress for future studies.

Preoperative pharmacological management of a patient with ASD II and pulmonary hypertension forcardiac surgery

The article presents the case of a 36-year-old woman referred to the Clinic of Cardiology at the Pomeranian Medical University with exertional dyspnoea that had been increasing for 2 years. Upon examination, the patient was diagnosed with an atrial septal defect type II (ASD II) with a left-to-right shunt and pulmonary hypertension. Echocardiography revealed a defect of 4.3 cm in diameter, right ventricular systolic pressure (RSVP) 80 mm Hg, tricuspid regurgitation. Right heart catheterization (RHC) revealed: mean pulmonary arterial pressure (mPAP) 59 mm Hg, pulmonary vascular resistance 10.22 Wood units (WU) and a negative vasoreactivity test. Following a cardiosurgical consultation, the patient was qualified for preliminary pharmacological treatment and re-examination. Sildenafil was included in the treatment, followed by macitentan. Improvement in exercise tolerance was observed [in the 6-minute walk test — from 440 to 526 m; clinically from New York Heart Association (NYHA) III to NYHA I/II] as well as a decrease in N-terminal pro-B-type natriuretic peptide concentration (from 250 to 170 pg/mL). Echocardiography showed a decrease in RVSP to 60 mm Hg. In RHC performed after one year of treatment, mPAP decreased to 40 mm Hg, PVR decreased to 3.25 WU, and cardiac output increased from 5.57 to 10.44 L/min. Mixed venous oxygen saturation increased from 64.5% to 72.5%. After another cardiosurgical consultation, the patient was qualified for surgery. Closure of ASD II was performed with a pericardial patch and completed with tricuspid valve plasty. The peri-and postoperative period was uneventful, and the clinical and echocardiographic follow-up confirmed the positive effects of the treatment.

Cardiac Septal Defects in Children: Hemodynamics, Clinical Manifestations and Detection

Cardiac septal defect in children is one of the congenital heart defects characterized by atrial septal defects (ASD), ventricular septal defects (VSD) and defects in both atrial and ventricular septum (AVSD). The hemodynamic changes that occur are caused by a left to the right shunt. Differences in location, size of the defect and pulmonary vascular resistance make hemodynamic differences and clinical manifestations between the three types of cardiac septal defects. Detection of cardiac septal defects can be done by clinical examination by listening to the characteristic heart sounds and murmurs for each defect. However, clinical examination alone is often still difficult to determine the type of cardiac septal defect so that several supporting examinations such as photothorax, ECG, echocardiogram and cardiac catheterization need to be done to help establish the diagnosis.
